A buried service splice enclosure for sealing a splice of telecommunication cables comprises a closure defining an interior space for accommodating the cable splice and defining an opening for receipt of the splice therethrough. A closure seal sealably closes the closure opening and has apertures for receipt therethrough of the cables. Means are provided for sealing the closure seal to the closure and for sealing the cables to the closure seal at the apertures. An inlet fitting, such as a check valve, communicates with the closure interior space and is adapted to receive and pass an encapsulant under pressure into the interior space. An outlet fitting, such as a pressure relief valve, also communicates with the interior space, the pressure relief valve adapted to pass the encapsulant therethrough when the encapsulant is exposed to a predetermined pressure in the closure interior space.

Enclosure for sealing a splice of electrical cables

A safety shield for capturing corrosive fluids escaping from joints or valves in piping systems consists of first and second shroud members releasably joined together to form an enclosed chamber in assembled position about the joint or valve. The chamber includes at least one aperture which is sized and shaped for mating engagement around the pipe. Corrosion resistant gasket members interposed between the first and second shroud members and between the pipe and the at least one aperture render the enclosed chamber vapor tight in the assembled position. The chamber may further include at least one other aperture sized and shaped to receive the operating stem of the valve therethrough, and a corrosion resistant gasket interposed between the valve stem and the at least one other aperture for forming a vapor tight seal without interfering with the operation of the valve. The first and second shroud members are releasably held together by adjustable bands which are tightened around the outer periphery of the shroud members so as to exert a substantially uniform pressure along the joining region between the shroud members. The safety shield may also include one or more outlets for discharging any fluid which may accumulate in the enclosed chamber.

Safety shield

A method for protectively enclosing electrical cables, wherein a portion of at least one cable is sealably disposed in the interior of a housing, includes the steps of placing a pressure-relief valve in communication with the housing interior, the pressure-relief valve being selected to pass an encapsulant therethrough on exposure to a predetermined pressure in said housing interior, and introducing an encapsulant under pressure into the housing interior until the encapsulant passes through the pressure-relief valve. The encapsulant introduction step is practiced by providing a pump having an inlet and an outlet, placing the pump inlet in communication with the housing interior and supplying encapsulant to the pump inlet directly from a bulk encapsulant container.

Method for protection of cable splices

A protective enclosure for use with one or more electric cables, comprises first and second elongate casings juxtaposed along respective end surfaces thereof to define a housing with an open interior, at least one electrical cable disposed in the housing interior in an encapsulant, the encapsulant filling the housing interior. At least one end closure is disposed in the housing and defines a cable passage therethrough, the cable being resident in part in the cable passage. Seal-effecting structure for providing sealed relations between the first and second casings, between the end closure and the first and second casings and between the end closure and the cable part, is inclusive of a cover plate disposed in confronting relation to the end closure and movable relative thereto.

Moisture-resistant cable splice and sealing structure thereof

A connection zone location and selection device is provided for application to first and second flat multiconductor cables secured to one another in overlapped relation. In such arrangement, the secured cables define a matrix of connection zones each having in registry therewith a distinct pair of conductors of the cables. The device is adapted for movement with respect to the cables and includes a punch for making perforations through the cables and locator indices for registration with a preselected location on the cables or with perforations made by the punch for disposing the punch in registry with selected ones of the connection zones. Methods and a kit of components for making undercarpet power installations are also provided.
